Abstract
1. Process for the continuous preparation of anhydrous crystalline dextrose characterized by the fact that a mass constituted by glucose syrup and anhydrous dextrose crystals is brought to pass through, from top to bottom and with malaxation, a crystallization zone of axis preferably substantially vertical in which said mass is subjected to a temperature gradient decreasing globally from 0.2 to 2 degrees C/hour from top to bottom possibly modulated, in which process the crystallization zone is supplied in the vicinity of its upper end, - on the one hand, with glucose syrup having a richness in glucose higher than 92 % by weight, a proportion of dry matter higher than 80 % and a temperature above 60 degrees C and, - on the other hand, with mass subject to crystallization which is taken up and recycled from an intermediate level of the crystallization zone, distant from the ends of the latter by at least 1/4 of the total length, the recycled amount of mass subjected to crystallization representing by volume from 40 to 110 % of the amount of glucose syrup introduced into the zone, at the level of the lower end of which there is continuously collected a crystalline mass rich in anhydrous dextrose crystals which are recovered.
